Test Set-up Connection
1. Connect the ADC32xx/ADC34xx EVM J13 connector to the TSW1400 EVM J3 connector
2. Connect 5 V to the TSW1400 J12 supply input connector and 5 V to the ADC32xx/34xx EVM J15
supply input connector
3. Provide a sample clock at the ADC32xx/34xx EVM J9 SMA connector
4. Provide a sine wave for the ADC32xx EVM J1 or J4 analog input and J1, J4, J5, or J8 of the ADC34xx
EVM
5. Connect a USB cable from the TSW1400 to the programming computer
6. For basic testing, the USB/SPI connection is not needed on the ADC32/34xx. Press SW1 to perform a
hardware reset. This will work with the default settings.
7. Verify the following jumper connections on the ADC32/34xx EVM:
•
JP1
– 2,3 default condition PDN is low
•
JP2, JP3, JP4, JP5
– Closed – default condition for SPI connection
•
JP6
– 1,2 default condition to select LDO power supply
•
JP7
– 1,2 default condition to select LDO power supply

ADC32/34xx and TSW1400 Setup Guide
See the
for more detailed explanations of the TSW1400 set-up and operation. This
document assumes the High-Speed Data Converter (HSDC) Pro software and the TSW1400 hardware
are installed and functioning properly.
The ADC32/34xx EVM requires High-Speed Data Converter Pro
software version 2.6 or higher with TSW1400 hardware of Rev D (or higher).
Single tone FFT test
1. Start the HSDC Pro GUI program. When the program starts, select the ADC tab and then select
ADC324x_2W_14bit.ini or ADC344x_2W_14bit.ini device in the
Select ADC
drop down menu.
Figure 16. Select ADC32xx or 34xx in the HSDC Pro GUI Program
2. When prompted with
Load ADC Firmware?
, select
YES
3. Select Single Tone FFT Test under
Test Selection
4. Select number of sample points (and resulting number of FFT bins) to be used. The example shown in
has 65536 samples.
